Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Pacifigeron rapensis faces severe threats from its extremely restricted range on Rapa Island in French Polynesia, making it vulnerable to any environmental disturbance. The species is threatened by habitat degradation from invasive plant species that alter the native vegetation structure. Climate change poses additional risks through potential shifts in precipitation patterns and temperature that could affect the delicate ecological balance of its montane habitat.
